Biogeochemical Processes Controlling Oxygen and Carbon Isotopes of Diatom Silica in Late Glacial to Holocene Lacustrine Rhythmites
Hernández, Armand; Bao, Roberto; Giralt, Santiago; Barker, Philip; Leng, Melanie; Sloane, Hilary; Sáez, Alberto (Elsevier, 2010-05-19)[Abstract] Biogeochemical cycles and sedimentary records in lakes are related to climate controls on hydrology and catchment processes. Changes in the isotopic composition of the diatom frustules (δ18Odiatom and δ13Cdiatom) ... -
ENSO and Solar Activity Signals From Oxygen Isotopes in Diatom Silica During Late Glacial-Holocene Transition in Central Andes (18°S)
Hernández, Armand; Giralt, Santiago; Bao, Roberto; Sáez, Alberto; Leng, Melanie; Barker, Philip (Springer, 2010-02)[Abstract] The late glacial-Holocene transition from the Lago Chungará sedimentary record in northern Chilean Altiplano (18°S) is made up of laminated sediments composed of light-white and dark-green pluriannual couplets ...
